Backfill ci catalog index

What does this MR do and why?

The merge request adds a new migration to backfill the boolean ci_catalog index. The migration is batched with a batch size of 9,000 and a throttle delay of 10 seconds. Parent issue.

How to set up and validate locally

1. Checkout my branch
2. Check that none of the project's elasticseach data have the ci_catalog: (true/false) boolean by running project.__elasticsearch__.as_indexed_json on any of the project you have locally.
3. Run migration with Elastic::DataMigrationService[20231017171659].send(:migration).migrate
4. Validate that the boolean is present in projects with project.__elasticsearch__.as_indexed_json by finding ci_catalog value set to either true or false depending whether the project is marked at catalog resource or not.
